Guanidinium 2-carboxy-6-nitrobenzoate monohydrate: a two-dimensional hydrogen-bonded network structure
MetadataShow full item record
In the structure of the title compound, CH6N3+烸H4NO6-爲O, obtained from the reaction of guanidine carbonate with 3-nitrophthalic acid, the 2-carboxylic acid group is deprotonated and participates in an asymmetric cyclic R21(6) hydrogen-bonding association with the guanidine cation together with a bridging water molecule of solvation. A conjoint R12(7) facial association involving a nitro O-atom acceptor together with a further five guanidinium N-H...O hydrogen bonds, as well as a strong carboxyl-water O-H...O interaction [2.528 (3) ŝ, give a two-dimensional network structure.
